JOURNAL-BOX WEAR PLATE. l

applicati@ med november as, 192s. Serial No. 70,923.

My invention relates to railway rolling stock and consists in an improved journa box wear plate or pedestalliner.

In railway trucks there is usually prob vision for relativewnove'ment between the box and the pedestal with which the box is assembled, and. in some types of trucks the relative movement between these parts is so' .great that wear on one or the other or both of the parts soon increases the clearance ordinarily provided between the parts te such an extent that the play between the two parts is objectionable.

The main object of my present invention is to provide a simple economical device for preventing wear on the sides of the box or the legs of the pedestal, or, in they event that such wear has taken place, to take up the play thus created.

Additional objects of my invention are to provide in a device of the type referred to means for seating and positioning springs or equalizers or other truck parts usually rest-` ing upon the top of the journal box.

In the accompanying drawlngs illustrating; my invention,`

igure 1 is a top view of a box equipped,

with my improved wear-plate.

Figure 2 is in part a side elevation and in parta longitudinal vertical section through the box and wear plate. .i v

Figure 3 is a transverse section through the box, wear plate, and a spring mounted on the box and showing part ofthe pedestal with which the parts are assembled.

Figures 4, 5, and 6 illustrate a modification of my invention and correspond to Figlires.` 1, 2, and 3 illustrating the preferred.

structure, no portion of the box or edestal being shown, yand indicating the equ izerbar. Figures 7, 8, and 9 similarly illustrate a further modification rof my invention:

Figures 10, 11, and 12 similarly illustrate another modificationv of my invention. Fi ures 13, 14, and 15 similarly illustrate anotger modification of my invention.

In Figure lvthe journal `box indicated at 1 is of usual construction and is shown with a flat to and flat sides. A relatively thin plate'2 aving a general U-shape structure fits over the box, engaging the top and sides thereof, and reerably is providedfat front andback wit flanges 3 extending at'right angles tothe body of the plate and adapted I6 to engage the front and rear faces of the the box. l

The body of plate 2 forms a seat for spring 7. The lower ends of the vertical legs. ofthe plate are cut away in part to form projections 8 which are bent inwardly and then outwardly as indicated in Figure 3 to provide a yielding clip for engaging the lower corners of the box to retain the on the box and prevent any vertical shi in of the plate on the box. These clips would be of special value in the shipment of boxes with plates applied and before they are assembled with the other truck structure.

In the modification illustrated in Figures late 4, 5, and 6 the wear plate 9 is ada ted to support and position an equalizer ar 10, the underside of the end of which vhas a groove which is engaged by a corresponding ridge 11 struck up in the top portion of the plate. It will be noted that one or both vertical'legs of the plate are cut away as indicated. at Y12 to clear the adjacent portion of the equalizer.

In the modification illustrated in Figures 7 ,.8, andA 9, the wear plate 13 is adapted to seat and position a leaf spring 14 and is provided with a suitable frame 23 spot- Welded to the wearl plate at the points W. The frame 23 is rectangular in shape with the sides 23a at front and back of journal box of such height .that they not only position. the

spring but, 1n 'the event of breakage of the spring, they limit the downward movement of the truck frame normally supported by the spring.

Figures 10, 11 and 12 illustrate a modification in whicha separate spring seat 15 is mounted upon the wear plate 16 and serves to center the coil spring 17 and decrease the xso thrust ofthe same and any wear due to shifting movement of the lower spring coil. This construction permits the provision of a continuous flange 15 surrounding the lower coil of the spring.

In the modified structure shown in Figures 13, 14, .and l5, the wear plate 17 is prothroughwhich a rib 19` on lthe box 20 may vided with a slot 18 in vits upper portion rojectiand engage a `groove in the underace of tbe'end of the equalizer 21. Suit` able projectlons 22 are provided in the wear plate at each end of slot`18 and serve to position the equalizer lengthwise of the box.v

In all of these forms the objects of my invention set forth at the beginning of this specification are attained, and it will be seen that the provision of my Wear plate im the original truck assembly will protect the box and, if the wearV plate ismade of softer material than the pedestal, will protect the pedestal jaws from wearing, thus eliminating the necessity of providing hardened faces on the pedestal jaws.

When a wear plate is worn out, it may be replaced at a trilling cost compared with the cost fof replacing a journal box or pedestal. Due to the slight cost of liner or wear plate replacementa'the fit between the journal box and the pedestal may be better maintained and accelerated wear of the parts, which follows increase in the clearance between box and pedestal, may be eliminated.

Various modifications and details of my invention other than those shown by me may lie-made without departing from the `spirit of'my invention, and I contemplate the exclusive' use of such modifications as fall within the scope of my claims.

I claim:

1. As a new article of manufacture, a oncpiece Wear late adapted to be applied to and remove from a standardA.R.A.journal box for railway trucks to prevent contact between the sides of the box and the truck pedestal, said plate including means for engaging the top and both sides and the bottom of the box so that they move together in the pedestal.

2. As a new article of manufacture, a sheet metal wear plate applicable to a standard A. R. A. journal box and adapted to overlie the top and both sides of the box, the front and back portions of said plate being llanged toengage front and rear faces of a pedestal, and means on said plate for causstraddle an A. R. A. journal box and to overlie the top and both sides of the box, the front and back portions of said plate being flanged to engage adjacent front and rear faces of a pedestal, and the lower ends ot' said plate being inclined so as to engage. adjacent box corners to cause the plate and box to move together in a pedestal with,

which they are assembled.

5. A U-sliaped wear plate adapted to straddle a journal box and overlie the top and sides ot' the box, each of the ends of the plate being bent .inwardly and outwardly to form retaining clips adapted to slip over the top corners of t-he box and to engage the lower corners of the box.

6. A vU-Shaped wear plate adapted to straddle a journal box and overlie the top and sides of the box, each of the ends of the plate being cut away for a portion of its extent and the remaining portions beingbent inwardly and outwardly to form spaced retaining clips adapted to engage the lower corners of .the box.

In testimony whereof I 'hereunto ailix my signature this 17 day of November', 1925.

PFLAGER.
